2020 GMC ACADIA Complaints

I bought my car [XXX] it had 7 miles. I loved my car. Then in January 2021 things just went crazy. It started with park light on. My forward brake assist warning didn’t work, my back up camera in and out . My braking and stability were on and off. Then weird codes like. Engine at half power, unable to shift soon and speed control out. Then if I hit a bump message went away and speed control back on. I’ve taken care into another GMC dealer because dealer I bought my car at , closed up and took off!! Took it to closet dealer. Not long after repairs same issues started! So many different problems all at once! I have been treated horribly during these issues by dealership and extended warranty company. Dealer had my car for 3 weeks ! They couldn’t figure out the problem. I sat there for 4 hrs sent me home told to come back for 9 mile test! Why in 4 hrs that wasn’t done. So again the unable to shift message back on! I get in my car it starts but won’t shift ! Dealer charged me 250 to tow to shop! When they said I’d be fine ! I had more issues again and again! I’ve been driving over 40 yrs no accidents. I bumped into someone during a huge traffic jam in Ohio! Braking didn’t work no warning even . I should speak to a lawyer and could explain more to a person on filing these complaints.

Backup camera continues to intermittently fail even after recall remedy was performed. When placing the car in reverse, the backup screen goes black with a warning symbol on the screen that the camera is not working. This has happened intermittently for the last couple years. I've taken it to a GMC service center 5 times for this issue (3 of these visits were after the recall remedy was performed). The service has fixed the issue but it only lasts for a short time before reoccurring.

The car has parking brake on unable to disable.Have to put in drive force the system to move. Same with reversing the car. Air bags not working. Seat belt restraint on when we are wearing them. Left turn signal failure. Steering limited caution sign on. ESC sign on. Engine light on. Transmission unable to shift soon light on. Traction lights on. ABS brake light on. Temp says -40 degree when 30 out. I’m finding this unsafe to drive. Call GMC that told me to start On Star diagnostic. Pull up at least 4 codes And today the transmission indicators came on. Not sure what to do. The car has low miles. But I have stopped driving as of today due to break down or serious malfunction while driving.

Code P0128. While driving the vehicle gives a "steering assist reduced drive with care" the engine coolant temperature gage goes to 0 and the cooling fan runs until you turn off the car, and the a/c stops working. After replacing the engine coolant temperature sensor and harness the vehicle still does it. There are hundreds of reports of this happening online in forums. This is a safety issue when the vehicle is being driven.

The contact owns a 2020 GMC Acadia. The contact received notification of NHTSA Campaign Number: 22V709000 (Back Over Prevention) however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was made aware of the issue and confirmed that parts were not yet available. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The contact had not experienced a failure. The VIN was not available.

My steering assist is reduced drive with care message is on. The AC is no longer working and the fan is constantly running and sounds horrible. The temperature gauge has not come off of cold. After researching this issue online-it looks like this is a constant problem with Acadias from 2017-current. People are talking about the cost being between $1100-2400 to fix. There is a service bulletin out about this issue(17-NA-158) May 2017 If GMC knows that this is a problem why are they not recalling them?? My car was purchased brand new and of course is out of warranty like most others(the extended warranty doesn’t cover it either) GMC needs to recall these vehicles and fix this issue!!!!!

Service indicator on the driver information center stating to service vehicle detection AKA blind spot alert the system has failed once already was taken in for repair to GM was repaired and it has now failed again and is going in for service on April 4th 2023
